When you export a Microsoft SQL Server Reporting Services (SSRS) report to a Microsoft Excel workbook, there are hidden rows or columns in the workbook. The following image is an example of this problem:

This problem occurs because row heights or column widths are rounded.
Report Definition Language (RDL) enables you to use several measurement units (for example, inches, pixels, centimeters, and points) to specify position and size values. However, Excel uses only points. Therefore, the SSRS Excel rendering extension converts the height and width of the table, the heights of the rows, and the widths of the columns to points. This process may include rounding some values. In this situation, the table height or width and the sum of the row heights or column widths are different. To compensate for the difference, the SSRS Excel rendering extension inserts a small row or column to the workbook.
To work around this issue, specify the measurement unit in points.
Note You can convert other measurement units to points. For example, you can convert inches to points by using a ratio of 1 inch to 72 points.
